martyr Posted March 11, 2015 Share Posted March 11, 2015 (edited) Hello everyone, I am trying to sniff a network. Adapter TL-WN722N Target AP signal: %80-85 Target network topology: 1 router, 15 clients (mostly windows) My steps are: echo 1 > /proc/sys/net/ipv4/ip_forward airmon-ng start wlan0 going to /etc/ettercap/etter.conf to set: ec_uid = 0 ec_gid = 0 -- Commenting out iptables # if you use iptables: redir_command_on = "iptables -t n.... redir_command_off = "iptables -t ...... and then ettercap -G Sniff -> Unified Sniffing, selecting adapter wlan0 Hosts -> Scan Hosts -> Add victims to target list and then MITM->Arp and then Start->Start Sniffing And then running dsniff -i wlan0 to sniff interesting packets... Okay everything works great until here. Sometimes, ettercap kills the connection of client. As far i understand, i am forwarding packets with ARP Poisoning. So here are my questions: - Is that possible to sniff network in "passive" or "unoffensive" mode? Ettercap has "Unoffensive" option but if i go with that, i can't scan hosts. I can't understand by. - My purpose is that just sniffing network, not ALTER or EDIT any packets. Just sniffing. - How can i start a proper sniffing? My target AP has %80-85 signal quality. No packet loss to gateway. Any suggestions would be great. Thanks. Edited March 11, 2015 by martyr Quote Link to comment Share on other sites More sharing options...
